Gravity in our universe

Gravity is a fundamental force that attracts and holds objects together. Earth's gravity pulls everything towards its center, including the moon, keeping it in orbit. The Sun, with its massive gravitational pull, keeps all planets in the solar system in their orbits. Our galaxy, the Milky Way, contains about 200 billion stars, each exerting gravitational forces that hold the galaxy together. Beyond our galaxy, gravity is the force that maintains the structure of billions of galaxies in the universe, making it one of the most crucial forces in existence.
